Benefits of technology

[0022]In a 2010 and newer HHDD engine application, the HHDD comes equipped from the factory with DOC/DPF and SCR after-treatment systems. The upfit of the present invention comprises the Exhaust Thermal Management System (ETMS) and Dual Fuel system. The ETMS and Dual Fuel systems provides the newer HHDD engine system with means to reduce the criteria pollutants well below current standards as well as means to achieve rapid heating at “key

Problems solved by technology

Because these configurations utilize “high-pressure” direct NG and diesel fuel injector systems, they are very costly and have had a history of poor reliability.
These configurations have modest cost but lack the NG metering precision needed to attain compliance with U.S. EPA and CARB regulated exhaust emission standards.
These systems can be expensive and rely fully on digital information from their mixed-fuel

Embodiment Construction

[0032]In the embodiment employed with 2010 and newer HHDD engines, the APG V6000 (or V6000) 1 (FIG. 2) of the present invention in its simplest embodiment is combined with a 2010 or newer Heavy-Heavy Duty Diesel (HHDD) engine 110 and comprises and APG Dual Fuel system 120 substituting an amount of natural gas (NG) 25 for diesel fuel 130 (see FIGS. 2, 2a and 2b.) and an exhaust thermal management system 500 comprising means to rapidly heat the factory-provided DOC / DPF and SCR systems.

[0033]For pre-2010 HHDD engines the APG V6000 is combined with a pre-2010 Heavy-Heavy Duty Diesel (HHDD) engine 110 and comprises an APG Dual-Fuel system 120 for substituting an amount of natural gas (NG) 25 for diesel fuel 130 (see FIGS. 2, 2a and 2b.). The APG V6000 1 comprises, a “full” after-treatment system 220, and at least one Electronic Control Module(s) (ECM's) 320, with appropriate software 330, utilizing multiple Communication Area Network (CAN) channels to precisely control NG 25 fuel substit...

Abstract

The present invention provides up-fit after treatment technology for bringing Heavy-Heavy Duty Diesel (HHDD) engine powered vehicles into compliance with the Title 13 CCR, Part 2025 mandate (meeting 2010 criteria emission standards). It also includes a Dual Fuel system, Exhaust Thermal Management System further reducing: NOx constituents, consumption of diesel fuel, particulate matter and CO2 emissions. The invention further comprises multiple sensors that provide data to electronic control module(s). The APGV6000 enables rapid after-treatment thermal activation, compares “real-time” sensor data with target data, and adjusts the after treatment system and/or dual fuel system and/or Exhaust Thermal Management system to produce exhaust emissions well below 2010 exhaust emission standards. For 2010 and newer HHDD engine applications, the V6000 comprises the Dual Fuel and exhaust thermal management system to affect rapid after-treatment activation, reduced NOx emissions well below, 2010 (current) standards, reduce diesel fuel usage and reduce CO2 emission.
